X710 LCD & nanopi m3

Hi,

This is a cross-post from friendlyarm.com forum - no response so far, maybe
will be more lucky here.

I'm using this screen with M3 on debian. How can I change screen brightness
(backlight) or how can I switch the screen completely (not blank it - as I
see, the backlight is still on)?
Using /sys/ filesystem or any other programmatical method.

Thanks

Kuba

Hi，Command line input: echo 15> /dev/backligh
When the 1-127 is sent to the backlight device, you can adjust the
brightness of the backlight; 127 of which is the brightest, usually about
15,
You can see some of the images in the dark, for 1-15, the basic black
piece. When greater than 127, will be treated as a 127, also is the
brightest.
